"Many players want to make as much money as they can and change teams for ten grand," rapped Giggs.
"How is that going to make much difference to their lives? Foreign players always have their home somewhere else, so they are going to have their eyes on going back.
"But for the likes of me, Gary Neville and Paul Scholes, this is our home."
Giggs, 34, admitted he would totally understand if fans are disgusted at the cash being thrown around.
He added: "Yeah, I would. If you get those players on their own they are good lads.
"So a lot of the blame has to go on their advisors and agents who make a lot of money out of these deals and don't have the interests of the player at heart."
Ronaldo has spent all summer being courted by Real Madrid - angering boss Alex Ferguson.
The Portuguese winger has been given an extended break following Euro 2008 and has also had ankle surgery. Giggs' own flirtation with a big-money move abroad never extended beyond a tentative inquiry from AC Milan a decade ago.
He told the latest issue of GQ magazine: "Maybe one day I'll regret it but at the moment I feel very happy I've stayed here."
